when the oneness unzips itself, it becomes "bad" and "good", to attain peace zip these back together. Look at the effect of those beliefs you enjoy most, both good and bad. The good effects show you it's not all bad, the bad effects show you it's not all good, reaaly appreciate the suffering that comes from your beliefs and the enjoyment will fade away, appreciate the enjoyment that they gave you and you will feel no guilt as you zip them together and vanish the desire.
